Description of the development:
()
The system consists of remote strain (displacement) gauges, interface block, hand-held controller, and end terminal. The original strain sensors are based on the principle of change in natural oscillations of a string depending on the value of its tension. Via a communication line, the interface block controls data reading from a group of sensors and data transmission to a control terminal. Data on local strain in locations of installing the sensors in transmitted from a group of interface blocks positioned in control-measuring columns to the control terminal where the data is analyzed. The data received at the terminal indicates a possibility of critical deformation and stress resulting from soil shearing, corrosive metal loss, inadmissible cracking, peak overloading, ect.
